SPECIFICATION forming part of Letters Patent No. 707,701, dated August26, 1902.

Application filed April 25,1901. Serial No. 57,453. (No model.) i

To all, whont it may concern.-

Be it known that I, GEORGE M. JACKSON, a citizen of the United States,residing at Catharine, in the county of Schuyler and State of New York,have invented a new and useful Separator, of which the following is aspeciiication.

My invention is an improved machine for separating beans, grains, seeds,and the like; and it consists in the peculiar construction andcombination of devices hereinafter fully set forth and claimed.

Figure 1 is a perspective view of a separating-machine constructed inaccordance with my invention. Fig. 2 is a rear elevation of the same.Fig. 3 is a detail transverse sectional View taken through theseparatingrollers.

In the embodiment of my invention I employ a pair of separating-rollers1, which are disposed side by side, inclined longitudinally,

and are journaled in suitable bearings 2,.

which bearings are laterally adjustable in the front and rear sides of asuitable casing 3, which latter is here shown as supported on a frame 4.In operation my improved separating-rollers rotate in oppositedirections, the inner contiguous sides thereof moving upwardly, asindicated by the arrows in Fig. 3. Any suitable means may, within thescope of my invention, be employed for thus rotating theseparating-rollers. As here shown, the said separating-rollers areprovided at the rear ends of their shafts with pulleys 5,

which are connected to pulleysG on a-driving-shaft 7 by suitable endlessbelts 8. The said driving-shaft 7 is journaled in bearings in the framea and is provided with a flywheel 9, having a crank-pin 10. A suitabletreadle 11, which is mounted on one side of the frame, is connected to.the crank-pin by a pitman 12. Thereby the machine is operated, as willbe understood.

A suitable feed-hopper 13 is disposed above the upper ends of theseparating-rollers. As here shown, said hopper is supported at its endsby standards 14, which rise from the sides of the casing 3. A shaker-bar15 is secured to and depends from the rear side of the feed-hopper andis provided at its lower end with a vertical slot 16, in which operatesa stud or pin 17, that is carried by one of the tween the said rollers.

pulleys 5. Said shakerbar 15 operates a suitable agitator in the hopper,which is thus caused to discharge its contents evenly and continuouslyon the upper portions of the separating-rollers. I do not desire tolimit myself to the means hereinbefore described in this connection, asany othersuitable means may within the scope of myinvention be employedfor this purpose.

Below the lower ends of the separating-rollers is a spout 18, whichdischarges onto an endless traveling conveyor 19, which comprises a beltor apron 20 and rollers 21 22, which support and operate said apron. Thesaid endless traveling conveyer is disposed in a suitable frame orcasing 23 at the front side of the frame 4. and open on its upper side,so that the upper lead of the conveyor can be readily seen by theoperator. The roller 22 has a pulley 24: at one end of its shaft, whichis connected by an endless belt 25 to a pulley 26 on the driving-shaft7. The upper lead of the endless conveyor travels outward from theseparating-rollers and discharges into a suitable spout 27, which leadsto any suitable receptacle.

In the operation of my improved separating-machine the materials to beseparated are discharged from the fced-hopperonto the upper portions ofthe separating-rollers. The latter are suitably spaced apart by theadjustable bearings 2, and as the rollers rotate in the mannerhereinbefore described their upwardly-moving opposing sides prevent thelarger particles from passing between them, thesinaller particles bygravity dropping be- The inclination of the latter causes the largerparticles which are retained thereby to slide downward between them andto be finally discharged from the lower ends of said rollers into thespout 18 and by the latter onto the conveyor. By observing the latterthe operator can note the operation of the machine and make suchadjustment of the rollers as may be required from time to time to securethe best results. Any suitable receiver may be placed under theseparating-rollers to catch the smaller particles which fall through thespace between them.

My improved separating-machine is exceedingly efficient in sorting orsizing beans,

peas, and the like and for separating grains and seeds of various kinds.

Having thus described my invention, I claim- I. In a separating-machine,the combination of a pair of inclined separating-rollers disposed apartbut in proximity to each other, to permit small particles to dropthrough the space between them, means to rotate said rollers in oppositedirections so that their opposing sides move upwardly to prevent largerparticles from becoming crushed between them, laterally-adjustablebearings for the rollers, to vary the width of the space between them, ahopper to discharge onto the upper ends of said rollers, and ahorizontallydisposed endless traveling conveyor having its inner sidedisposed under the lower ends of said rollers, substantially asdescribed.
